The Queen wore a powder blue Stewart Parvin outfit and a matching Philip Somerville-designed hat. She also wore her Brigade of Guards Badge, which she wears every year. The Duke of Edinburgh wore morning dress instead of full uniform, and sports a Household Division tie, Garter Star and Medals.

Queen Elizabeth II and Prince Philip, Duke of Edinburgh arrive at Horse Guards Parade for the annual Trooping The Colour parade on June 17, 2017 in London, England.

The Prince of Wales, riding horse George, wore the Guard of Honour uniform. The Duke of Cambridge wore his Irish Guard’s Tunic with Jubilee medals, sword and bearskin, and rides Wellesley.

Before the event kicked off, the Queen and Philip led a minute of silence on the Place grounds. The Queen also issued a solemn but ultimately uplifting message to people of Great Britain following a month of tragedies — including two terrorist attacks and a deadly apartment tower fire.

“Today is traditionally a day of celebration. This year, however, it is difficult to escape a very’ sombre national mood. In recent months, the country has witnessed a succession of terrible tragedies,” she said.

“As a nation, we continue to reflect and pray for all those who have been directly affected by these events,” the Queen continued. “During recent visits in Manchester and London, I have been profoundly struck by the immediate inclination of people throughout the country to offer comfort and support to those in desperate need.

“Put to the test, the United Kingdom has been resolute in the face of adversity. United in our sadness, we are equally determined, without fear or favor, to support all those rebuilding lives so horribly affected by injury and loss.”

She signed the message simply “ELIZABETH R”

After the parade, the entire royal family gather on the balcony of Buckingham Palace for the “flypast” of roaring jets. And, of course, that’s when we’ll get a glimpse of Prince George and Princess Charlotte.
